These stars can change the game completely on their day.

The transfer window has slammed shut for summer 2020 and there was plenty of movement on the final day as Bundesliga clubs looked to get their squads in order for the 2020/21 campaign. But who were the biggest arrivals on deadline day?

Here are the top five players who joined Bundesliga on deadline day.

Douglas Costa

Age: 30
Bayern Munich (on loan)

No, you’re not suffering from deja-vu, it’s more that history has reversed itself as Costa re-joins Bayern on loan from the club he originally left Munich on loan for, Juventus. The Brazilian first put pen to paper on a deal at the Allianz Arena in 2015 after a trophy-laden half decade at Shakhtar Donetsk. In Pep Guardiola’s final year with Bayern, the rapid winger scored seven goals and provided 18 assists in 43 competitive appearances as the Bavarians won the domestic double and reached the semi-finals of the UEFA Champions League.

He had a hand in another 10 goals when retaining his Bundesliga crown the following year under Carlo Ancelotti, before going out on loan to Juve in 2017/18. The deal was made permanent from the next season, and he continued his league-winning exploits in all three seasons there. Now the Brazilian is back in Bavaria and looking to keep that run going: “I’m glad to be back at Bayern again. I had a wonderful time in Munich with plenty of success, and am sure we’ll win yet more titles.”

Matteo Guendouzi

Age: 21
Central midfield
Hertha Berlin (on loan)

Hertha were also busy on deadline day, but as the club itself said, this was the one everyone had been waiting for. The young French midfielder joined on loan from English outfit Arsenal, stating his aim was to “progress personally and also help the club as a whole take the next step”.

Although just 21, the former Paris Saint-Germain youth product arrives with over 80 senior appearances for the Gunners and is a key member of France’s talented U21 side. A robust player whose job it is to clean up in front of defence, he could be what the Berliners are looking for as a partner to fellow summer signing Lucas Tousart.

Justin Kluivert

Age: 21
Position: Winger
Joined: RB Leipzig (on loan)
From: Roma

We already have Lilian Thuram’s son Marcus in the Bundesliga at Borussia Mönchengladbach, and now Justin Kluivert has rocked up at Leipzig, making some people feel very old having once watched his father Patrick for the Netherlands, Ajax, AC Milan, Barcelona and more. Also a product of the Ajax academy, the highly sought-after winger has joined Die Roten Bullen from Italian side Roma.

“Leipzig demonstrated that this was the ideal place for me to develop and take the next step in my career and help the team. My goal is to get games under my belt here,” the two-time Dutch international said of joining Julian Nagelsmann’s side – a team renowned for only signing young players and improving them. Expect to see plenty of the famous surname in action in the Bundesliga.

Eric Maxim Choupo-Moting

Age: 31
Position: Forward
Joined: Bayern Munich
From: Free agent

Another clever piece of business by the record champions saw the arrival of free agent Choupo-Moting following the expiration of his contract at Paris Saint-Germain. There have long been questions about having a back-up striker to Robert Lewandowski and allowing him a breather from time to time. Joshua Zirkzee has been that man recently, but Cameroon international Choupo-Moting comes as ready-made cover on a one-year deal, with both Bundesliga experience (over 200 appearances for Hamburg, Nuremberg, Mainz and Schalke), as well as abroad with Stoke City and PSG.

“He gives us the squad depth we need in the centre of our attack,” said Bayern sporting director Hasan Salihamidzic. However, the former Germany youth international also provides cover across the whole front line, which will be even more critical in the compressed 2020/21 campaign, with Bayern looking to defend all three titles, as well as competing in the planned FIFA Club World Cup at some point over the season. As Salihamidzic said, it works out well for both parties.

Ryan Sessegnon

Age: 20
Position: Left-back/left wing
Joined: Hoffenheim (on loan)
From: Tottenham Hotspur

Bundesliga clubs love their young English players right now, so it wouldn’t have been deadline day without one putting pen to paper on a contract in Germany. And what a signing it was by Hoffenheim as they brought in highly regarded left wing-back Sessegnon from Tottenham on a season-long loan, with the 20-year-old seeking regular playing time at the highest level. “It’s a club that produces young players into big players in one of the most competitive leagues in the world, so I’m happy to be here and can’t wait to get going,” the new TSG man said on his decision to choose the club over other suitors.

Sessegnon first burst onto the scene as a 16-year-old with Fulham, becoming the first player born in the 2000s to score a goal in the English professional leagues. His star continues to rise at the 2017 UEFA European U19 Championship, which England won in Georgia. He’ll meet a familiar face from that tournament in his first training session in Sinsheim, having scored a brace against Dennis Geiger’s Germany in the group stage from a more advanced left wing position.
